i-Med - How medical electronics will deliver
patient power

Society Faces Major Health Challenges
Fewer Younger People
Obesity and Sedentary Lifestyle
Fewer carers lower social and health insurance
income
Increased prevalence and earlier onset of chronic
diseases
3
Healthcare is changing

• Healthcare infrastructure was set up to manage
  acute illness, today 70 to 80 of the healthcare
  budget is spent on chronic diseases.
• Better more flexible monitoring of patients
• Migration of the care from the hospital to the
  home

4
Patient Monitoring Early Warning

• BMJ on Early Warning Scores 84 of patients had
  documented observations of clinical deterioration
  within eight hours of cardiopulmonary arrest
• RM Schein 1990 70 of patients have respiration
  problems 8 hours before circulation stops
• C Franklin 1994 66 of patients show abnormal
  symptoms 6hrs before circulation stops
• The doctor was warned in 25 of cases

5
Patient monitoring today

• Cable management, infection control
• Care areas, patient comfort and distress

6
Medical Body Area Networks (MBAN)a network of
wireless sensors around the body

• Clinical Benefits
• Patient mobility and comfort
• Monitoring flexibility
• extending monitoring into all care areas.
• Infection control
• Low cost disposable monitors
• Patient identification and tracking

MBAN Challenges
Robust wireless links
Capacity for Patient and Sensor density
Co-existence with other radios and networks
Days of continuous use from small light weight
devices (batteries)

Future MBANs IEEE 802.15.TG6 (MedWin)

• Members Toumaz, GE Healthcare, Philips
  Healthcare, Texas Instruments.
• FCC new MBAN service 2360 to 2400MHz band
• 2360-2390 MHz MBANS operations limited to health
  care facilities outside exclusion zones (indoor
  use only)
• 2390-2400 MHz  MBANS operations permitted
  anywhere (all hospitals, in-home, mobile
  ambulances, )
